On Sunday, May 22, San Francisco will mark the 30th anniversary of when the first AIDS case was reported in the city. To reflect on the occasion, Twin Peaks will don a giant red ribbon, similar the pink triangle seen each Pride weekend. BAR reports: "San Francisco AIDS Foundation CEO Neil Giuliano, Supervisor Scott Weiner, volunteers, and others will gather Sunday, May 22 at Twin Peaks Viewpoint. Installation begins at 8 a.m. The dedication ceremony will be at 11 a.m." The ribbon, visible across the Bay Area, will remain up from May 22 to June 19.

Some AIDS ribbon fun facts:

- It was inspired by the yellow ribbons memorializing U.S. soldiers serving in the Gulf war,

- Red was chosen for its connotations to blood and passion.

- The red ribbon was first used in the war on drugs. "The Red Ribbon was first used as an awareness symbol made by after DEA Agent Enrique S. Camarena was kidnapped, tortured, raped and murdered while working undercover in Guadalajara, Mexico. Citizens in his home town of Calexico, California donned the ribbons to emphasize the need for increased prevention efforts."

- When assigned to the AIDS Crisis in the 1980s by Visualize AIDS, no individual was credited as the creator of the Red Ribbon Project in order to assure anonymity.

- The red ribbon is copyright free, so that individuals or organizations would not profit from it.

- The first celebrity to publicly wear the ribbon was Jeremy Irons at the 1991 Tony Awards.
